How to Make Unlimited Lava in Minecraft With Dripstone
Lava can't be duplicated like water, but dripstone over a cauldron refills forever. How to make unlimited lava in Minecraft, with real fill times.
You can’t duplicate lava the way you duplicate water. Two lava source blocks side by side don’t make a third in normal survival. The only renewable lava is a dripstone farm: hang a pointed dripstone under a block, put a lava source on top of that block, and lava slowly drips into a cauldron below. Scoop it out with a bucket and it refills again, forever.
What you need for one module
- 1 lava source (a bucket of lava)
- 1 solid block to hold it
- 1 pointed dripstone
- 1 cauldron (7 iron ingots)
- A bucket to collect
Pointed dripstone grows in dripstone caves. Mine the hanging stalactites with any tool. Wandering traders sometimes sell it too.
Building a lava module
- Place a cauldron on the floor.
- Leave some air above it. The dripstone tip can be up to 10 blocks above the cauldron with nothing solid in between.
- Place a solid block above that space, and hang a pointed dripstone from its underside so it points at the cauldron.
- Pour lava on top of the solid block. The lava sits above the dripstone; the block between them holds it in.
- Wait. You’ll see orange drip particles when it’s working.
When the cauldron is full, use an empty bucket on it. A hopper under the cauldron won’t help here: hoppers can’t pull liquids, so collection is by hand with a bucket.
Contain the lava with non-flammable blocks on every side. A stray lava block next to wood will burn your farm down.
How fast it is
Slow. The lava only drips on random ticks, with a small chance each time. On average one cauldron takes roughly a full Minecraft day (about 20 minutes) to fill, and some take longer. That’s why real farms stack 10, 20 or more modules in a row, all sharing a lava “ceiling.” The farm also has to be within your simulation distance to work.
What the lava is for
- Fuel. One lava bucket smelts 100 items in a furnace, the best fuel per item you can carry. This is the main reason people build these farms.
- Obsidian. Pour water on a lava source to make obsidian wherever you want it, for portals or enchanting tables.
- Cobblestone and stone generators, which use flowing lava and never consume the source.
- Traps and mob farm kill chambers.
The Nether alternative
The Nether has lava oceans that are effectively endless. If you just need a few buckets now, build a Nether portal, walk to the shore at Y 31 and fill up. The dripstone farm is for when you want lava at home without the trip.

Common questions
Can you make an infinite lava source like water?
No. Two lava sources next to each other don't create a third in normal survival. A dripstone and cauldron farm is the renewable option.
How long does a lava cauldron take to fill?
It's random. The game rolls a small chance each time the dripstone gets a random tick, which works out to roughly one fill per in-game day per cauldron on average. Build many in parallel.
Do I need to stay near the farm?
Yes. The chunks have to be loaded for the dripstone to drip, so the farm only works while you're within simulation distance.
